Is it quite possible that the E1 on my rear AC/FURN was leading to all my confusion. With the E1 gone and AC1 and burner enabled I get these which are likely the correct results:
A call for hot water:
Lights: summer loop, domestic water
Summer pump runs
A call for zone 1 heat:
Lights: heat loop 1, zone 1 fan, zone 1 thermostat
Zone 1 pump runs
A call for zone 2 heat
Lights: heat loop 2, zone 4 fan, zone 4 thermostat
Loop 2 pump runs
The zone pumps don't seem to vibrate as much as the summer loop pump which I can't explain since they're all the same pump.
I tried the ice cube on the wet bay thermostat with no luck.
